Update:

Love playing with simple graphic shapes! I tweaked the composition a little bit and added stars. I felt the planet could fill the space more! But nice job! Your original was pretty solid to begin with!

Would you opposed to having the figures in motion. They look like they are just standing there. Maybe add one looking through the telescope and one running over. I do not know the back ground to this image and this could contradict the point of the pic. Good luck.

This is great! I would love to chime in and help out. Please take this all with a grain of salt as I'm new to this platform and way of giving off feedback. Took the time to try to scrappily mock-up some suggestions as well, see the attachment (somehow I wish you could embedded images in this chat thing). Feedback: • I feel it could use a bit more contrast as some of the mid-tone areas (ie: dark green-ish with grays) feel too close together. Perhaps your darkest shadows should feel closer towards a black hue, especially within that nice arc in side the lab - see my example • I like the guy in the foreground - he can stand out a bit more by enlarging him by maybe 30%. This can help more with bringing in perspective • I played around with the solar system above too. Ignore the amount of planets I have going on but I think my point is to try to spread out the planets and exaggerate the sizes a little bit more since there's a lot more room for them to own that space Hope this helps and good luck! Best, J
